Because of this fysical restriction i have often trouble to play Chopin-etudes: when one looks at photo's or drawings of Chopin's hand, one sees that he had really long fingers; So i did the black keys etude, and this was okey, and now i'm working the a minor 10/2;
I can relate this problem. My hands are probably anatomically well suited to playing piano... apart from my unusually short 5's. Very frustrating I must admit. But I have found that constanstly practicing a stretch does help alot. I can now just reach the 10th, whereas a month ago I couldnt.
